Joining a list of senior-level exists from Bharti Airtel in the last one year, since Gopal Vittal took over as chief executive, the company's Chief Technology Officer Jagbir Singh has resigned from his post, sources confirmed. Abhay Savargaonkar, who is currently the chief of network operations, will take over as the new chief technology officer following Singh's exit, sources added.

While Airtel neither confirmed nor denied the development, people in the know of the matter said that Singh is likely to move to another telecom operator in a new position.

As part of the restructuring, Akhil Gupta will be chairman of Bharti Infratel and vice chairman of Bharti Enterprises while serving on other Bharti boards.

Jagbir Singh, an Airtel veteran with a stint of more than 10 years in the company, held the post of director network services, and oversaw the networks and introduction of newer technology across Airtel's Indian and South Asian operations. He was also the member of the Airtel Management Board, the company's highest decision-making unit.

His successor, Abhay has also been at Airtel for over 10 years and has held various senior leadership roles covering the
